oxidobridged
Oxidobridged refers to metal complexes in which two or more metal centers are linked by a bridging oxide ligand, commonly described as a μ-oxido or μ-oxo bridge. In these species, an oxide ion coordinates to multiple metal ions, creating a M–O–M core. This motif is widespread in high-valent transition metal chemistry and in metal-oxygen clusters, including dinuclear and polynuclear complexes of iron, manganese, ruthenium, and other metals.
Structural characteristics include short M–O bonds, typically around 1.8–2.1 Å depending on the metals involved, and
Formation and relevance: Oxidobridged cores can form by oxidation of hydroxo-bridged precursors, hydrolysis of oxo precursors,
Distinction: The term emphasizes the bridging oxide as a functional connector between metal centers and is
